With the development of science and technology in China, seamless steel pipe is a new type of transportation equipment developed rapidly with the development of science and production technology in China. For this seamless steel pipe, industry experts said that this transportation pipe uses the principle of electromagnetic induction to transport liquid according to the electromotive force induced by the conductive medium through the external magnetic field.

　　For many enterprises using this transportation equipment, how to ensure the normal operation of seamless steel pipe is an essential link in the daily production process, and it is necessary to carry out daily maintenance of seamless steel pipe.

　　For normal enterprises, a relatively comprehensive inspection can be conducted on the seamless steel pipe once a year, not only from the appearance, but also from the key parts of the seamless pipe. Then a value of transportation shall be calibrated, and the voltage and circuit of the original parts of the pipe shall be confirmed, Ensure that there is no error in each link, so as to ensure the accuracy of pipe transportation in daily production activities. When inspecting this seamless steel pipe, it is often necessary to carry out zero drift. It is very necessary to adjust the zero point. Online zero adjustment must stop the flow of the transported liquid. In fact, it is not easy to do. Therefore, in the process of inspection, it is often necessary to check the operation of the sensor.
